| Popis: | (STEC) serotype causing human infections is sero-type O157:H7. However, increasing numbers of other STECserotypes, especially those of serogroups O26, O103, O111,and O145, are reported to cause severe diseases (9, 26, 27).Among cattle, non-O157 STEC strains are carried by aboutone-third of the animals (21). In outbreaks of STEC infection,the infection vehicle is usually contaminated or undercookedfood or water, and person-to-person transmission within fam-ilies is often seen. In sporadic cases, contact with cattle is oneof the major risk factors (22). Tracing of non-O157 strains toanimals has been reported in only a few cases (2, 5). The highprevalence and divergence of non-O157 STEC strains in cattleand the lack of selective culture media require molecularmethods for identifying the causative strain. In outbreak ortrace-back situations, the strain characteristics dictate themethodology. In this study, we describe tracing human O103:H2, O145:H28, and O174:H21 STEC infections to cattle farms.In Finland, all patients with STEC infection are asked abouttheir connection to cattle farms, and the contact farms aresampled for STEC. During the period from 2003 to 2006, fourcases of human non-O157 STEC infection involved contactwith cattle farms. A 7-year-old boy living on a farm raising beefcattle (farm A) was hospitalized with bloody diarrhea. STECO103:H2 |
